You will probably see results by the end of January. As I always say, stay in close contact with your ROO.
Monalbanol...your son's file will probably not be reboarded. He may be given credit for the Eagle, but I'm betting the file won't be relooked by the second board. Usually if the applicant doesn't get an offer they just stay in the pile, with the original score, and the files scored by the second board get added in, then Cadet Command designates a cut line to make enough offers for the second board. You stay in the running during the whole process, but your score usually doesn't change.
